256 GB DDR5 ECC RDIMM kit

This 256 GB kit contains eight 32 GB DDR5 registered DIMMs built for servers and workstations that require error-correcting memory. The modules operate at 4800 MT/s with a CAS latency of 40 and run at 1.10 V. They are intended for administrators who need maximum registered capacity in a single qualified kit.

Registered DDR5 stability under load

Registered buffering places a register between the DRAM and the memory controller, reducing electrical load on the bus during sustained read and write cycles. ECC circuitry detects and corrects single-bit errors in real time, preventing data corruption during long compute jobs. The 1.10 V operating voltage keeps power draw consistent across all eight modules.

Verify DDR5 RDIMM slot count and population rules

Confirm your motherboard provides eight 288-pin DDR5 RDIMM slots and supports 2Rx4 organisation at 4800 MT/s. Check the vendor memory qualification list for 256 GB total capacity with eight 32 GB modules. Ensure the platform BIOS is updated to the revision that enables full-speed operation for this density.

Questions about this item

How much power does the 1.10 V DDR5 kit draw under continuous load?

Each module runs at 1.10 V, the standard DDR5 voltage, keeping power draw low during all-day operation.

What motherboard feature is required for these 288-pin RDIMMs to function?

The board must support DDR5 registered ECC memory with 288-pin RDIMM slots.

Can the 2Rx4 registered modules share channels with unbuffered DDR5 DIMMs?

No, registered and unbuffered DDR5 cannot be mixed on the same channel.
